HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 464,850, dated December 8, 1891.

i Application filed October 20, 1890. Serial No. 368,629. (No model.)

`following is a full, clear, and exact description.

The object of the invention is to provide a new and improved hydrocarbon-burner which is simple and durable in construction, very eifective in operation, and permits the operator to change the intensity of the llame when# ever required, and also to direct the llame to any desired place in the furnace in which the burner is employed.

The invention consists in certain parts and details and combinations of parts, which will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation ofthe improvement as applied. Fig. 2 is an enlarged sectional plan view of the burner proper on the line oc in Fig. l, and Fig. 3 is an enlarged sectional side elevation of a modi lied form of air-pipe. V

The improved hydrocarbon-burner is provided with a casing A, extending into the opening B, leading to the interior of the furnace O, on which the hydrocarbon-burner is to be applied. The casing A is provided with suitable flanges bolted or otherwise secured to the outside of the furnace C, the outside of the casing being provided with athreaded flange D, in `which screws the air-supply pipe E, connected with a suitable source of airsup ply, usually a blower, forcing air through the pipe to the casing. The latter is also provided with an interior vertically-arranged iiange F, in which screws one end of an airfeed pipe G, extending concentrically into the main ai r-pipe E, asis plainly illustrated in Fig. l. Into this air-feed pipe G extends the inner end of an oil-supply pipe H, supn porting at its front end the burner I and passing at its rear end through an offset E, and a collar J 4held in the said offset by means of a set-screw J or other device. A The offset E is preferably formed on the bent part of the pipe E, and is so arranged that the oil-supply pipe H extends concentrically to the pipes G and E. The outer end of the oil-supply pipe H is preferably connected by a ball-joint with a faucet K, connected by a ball-joint with a verticallyfarranged pipe L, connected at its I lower end by a ball joint with the pipe N, connected with a suitable source of oil-supply. A handle or other means may be secured to the outer end of the oil-supply pipe lll, as

shown in dotted lines in Fig. l.

By the construction just described the oilsupply pipe H may be turned in its bearing in the collar J to change the angle of the burner I, or maybe moved forward and backward in the said collar by the operator wth out shutting oif the oil-supply. Thus the flame may be directed into the furnace at any desired angle, and when the air and oil are shut off the burner may be entirely withdrawn from the furnace. The supply of the oil to the oil-pipe H is regulated by the valve in the faucet K, so that a larger orsmaller quantity of oil is admitted to the pipe l-l, as desired. The inner end ofthe oil-supply pipe H is slightly contracted, asiat H', and from this contracted neck extends a plate I', forming a part of the burner I and provided at its front end with prongs l2, which extend al ternately upward and downward through the oil passing from the pipe H to facilitate its atomization.

Air-feed pipes G of various diameters may be used in the casing A to increase or diminish the intensity of the ame at the burner I. To make these pipes G interchangeable in the casing, Vthe said pipe is preferably pro vided with a threaded collar G', as illustrated in Fig. 3, adapted to screw onto the threaded flange F. For increasing and diminishing the bore of the collar G and the pipe G various sizes Of the latter may be used in the same casing A.

The operation is as follows: lVhen the several parts are in the position indicated in Fig. l and air is forced into the pipe F by .the blower or other means, then the air, in

erator opens the valve in the faucet K, the

IOO

oil flows from the pipe N through the pipe L and the faucet K into the oil-supply pipe I-l and through its contracted neck H onto the plate I of the burner I. The oil, as soon as it leaves the contracted neck H of the pipe, spreads on the plate I', and thus comes in contact with the compressed air, which moves it forward over the plate and onto the prongs I2, so as to be readily taken up and atomized by the air. lVhen the mixture is ignited, the iiame extends from the burner I through the inner part of the casing A and opening B into the interior of the furnace C. The iiame extends in a sheet from the burner I, and when the operatorturns the oil-supply pipe H he changes the position of the burner so that the flame varies its position correspondingly, and thus the sheet of ilaine may extend horizontally, in an inclined position, or vertically, as desired. It will further be seen that by moving the oil-supply pipe farther inward or outward, so as to change the position of the burner I in the pipe Gr, the intensity of the flame may be varied. This is due to the fact that when the burner I is near the inner end of the pipe G, as shown in Fig. l, compressed air rushing through the pipe G atomizes tlie oil more readily assaid oil rushes over the entire surface of the plate I and the prongs l2. When the oil-supply pipe I-I is drawn outward, then the force of the air on the oil is exerted on only part of the plate I, and thus the oil is not as thoroughly atomized as in the former case.y Thus the fire Within the furnace on which the burner is applied can be readily evened up at any desired part, at the same time insuring complete combustion.

I do not limit myself to the particular means illustrated for permitting the oil-supply pipe H to turn and to slide for the purpose mentioned.

Having thus described my invention, what I claim as new9 and desire to secure by Letters Patent, is-` l. A hydrocarbon-burner comprising'the main air-pipe having a bend and provided with the smaller concentric outlet-pipe-G, open at both ends, the sliding and turning oil-tube extending through the bend of the main air-pipe into the pipe G, provided on its front end with a burner proper and at its rear end with a faucet, a ball-and-socket connection between said faucet and oil-pipe, an oil-supply pipe N, and a pipe L, having a ,ball-,and-socket connection therewith at one end and with the faucet at its other end, substantially as set forth. Y

2. The combination, with the main air-pipe having a bend and a smaller concentricairoutlet pipe G, of a rotary and longitudinally movable oil-tube extending through thesaid bend into the pipe G and provided at .its inner end with an outlet and a plate to receive the oil, and terininatingin a series of prongs, whereby by turning the oil-pipe the angle of the plate may be changed, substantiallyV as set forth.

3. In a hydrocarbonburner, the combinal tion,witli the air-supply pipeand an oil-sup.- ply pipe having a contracted end', of aburner held on the said contracted endy and compris, ing a plate and prongs, substantially as shown and described. f'

4. In a hydrocarbon-burner,,the combination, with the air-supply pipe and anV oil-supply pipe having a contracted neck-,tof a plate extending from the said contractedneclgand alternately upwardlyand downwardly extending prongs formed on the front end of thesaid` plate, substantially as shown and described.
